NASA has released enhanced video from man\u2019s first walk on the moon in 1969.

The video was broadcast on television at the time, but most of the video recordings have \u00a0been locked away for nearly 40 years.

When Neil Armstrong made his first steps on the moon, it was viewed by what might have been the largest television audience ever--- more than half a billion people around the world.

But how the video was captured is a story in itself.

Because of skepticism of the time, NASA believed live video from the moon was crucial for credibility of the mission.\u00a0 And Stan Lebar of Westinghouse Electric was called on to develop the cameras that had to withstand the extreme conditions of plus or minus 250 degrees- AND they had to operate on very little power.

\u201cAnd the power was totally 7 watts, which is the power that one Christmas light bulb would take. And that, I might add, was a phenomenal achievement at that time.\u201d

The camera that captured Armstrong\u2019s first steps was mounted on a swinging door on the lunar module.

\u201cWhen Armstrong came out on the porch, he pulled a D-ring which opened a door, large door that had the camera mounted on it, so when the door swung out, the camera was positioned so it saw the ladder, and that\u2019s how that image was taken.\u201d

The video seen by millions was actually transmitted through a tracking station in Australia, then back up to a satellite, back to earth in Houston, and then to television networks.

The video released today comes from various so-called \u2018slow-scan\u2019 tape recordings made at the time found at NASA, the National Archives, and the CBS network archives.

The video was digitized and enhanced by the Lowry Digital Company.

\u201cIt\u2019s 37 years after the invention of the very seminal technology, video noise reduction, that John Lowry pioneered on the Apollo 16 and 17 missions\u2026 40 years from the Apollo project, and now we have the privilege to take this new enhanced technology that takes quality at a premium and tries to extract everything possible from motion sequences and bringing it back to NASA one more time.\u201d

\u201cOn the left is the available archive image now, dark image .. on the right, you\u2019re now starting to see the full body of Neil Armstrong coming down the steps. It\u2019s lightened up, there\u2019s more detail. You see his helmet now; you see the reflection in his helmet .. this is 3 weeks into the restoration and I think it\u2019s just amazing.\u201d

SUPER: Dick Nafzger, NASA, Restoration Team Leader

\u201cThere is nothing being created. There\u2019s nothing being manufactured. We are restoring and extracting data that\u2019s in the video. That\u2019s what Lowry does.\u2019

The release includes 15 key moments from Neil Armstrong's and Buzz Aldrin's historic moonwalk, including what\u2019s known as the flag-raising.

\u201cOn the left is a very good depiction of where we\u2019re headed. The noise, the lack of detail in the upper part, bottom part of the lunar module. If you look on the right, you start seeing a lot of detail that\u2019s clean. The surface of the moon is lit properly. This is the sun. It was a camera and scan converter issues on darkness \u2013there\u2019s\u00a0 your archival \u2013 this is what most of the world saw. Now we\u2019re looking at restored video and the detail on the lunar module and the astronauts and the overall picture clarity and cleanliness is coming along just terrific.\u201d

Nafzger points out that while they are releasing newly enhanced video, there was no \u2018missing\u2019 video discovered. He says all the video taken on the mission was transmitted to television in 1969.
